The purpose of this study is to evaluate safety of Targeted Lung Denervation (or TLD) in patients suffering from moderate to severe COPD. It is hypothesized that TLD will have a similar safety profile and improved physiological and functional outcomes to a sham-control.

A prospective, sequential two phase multicenter, randomized double-blind, safety, & feasibility study. The goal of AIRFLOW-1 will be to compare two energy doses and select the optimal energy dose to be utilized in AIRFLOW-2. The goal of AIRFLOW-2 is to compare the optimal energy dose to a sham control. All subjects will be followed for a minimum of 3 years.

The assessment of safety will be based on reporting of adverse events, particularly those adverse events that are respiratory in origin.

Device Success [ Time Frame: 6 months ]

Device success is defined as ability to deliver the test device to its intended locations, provide complete circumferential treatment and removal of the test device without the report of an adverse event during the procedure.
